目的研究白内障超声乳化术的特点、并发症及防治措施，总结了一组白内障超声乳化术的操作改进及随访结果。方法对４０例（４０只眼）白内障施行超声乳化小切口（６ｍｍ）人工晶体植入术，并采用周边旋转刻蚀法对硬核性白内障顺利完成手术。结果术后３～６个月，裸眼视力≥１．０者占５７．５％；≥０．８者占８２．５％；≥０．５者占９７．５％。术后平均散光为０．５０±０．２５Ｄ，小于同期内施行的４０例大切口（９～１２ｍｍ）对照组（Ｐ＜０．００１）。结论该手术不失为一种优于白内障囊外摘除术且安全、可靠的复明手术。
Objective To study the characteristics, complications and prevention and treatment of phacoemulsification and to summarize the operational improvements and follow-up results of a group of cataract phacoemulsification. Methods Forty cases (40 eyes) of cataract were treated with phacoemulsification with small incision (6mm) and intraocular lens implantation (IOL). Results 3 to 6 months after operation, uncorrected visual acuity ≥1.0 accounted for 57.5%; ≥0.8 accounted for 82.5%; ≥0.5 accounted for 97.5%. The average postoperative astigmatism was 0.50 ± 0.25D, less than the 40 cases with large incision (9 ~ 12mm) in the same period (P <0.001). Conclusion The surgery is a safe and reliable surgeries than extracapsular cataract extraction.
